Well, honestly everyone’s experience is different and their objectives different. There is a class of folks that @mrdecibel alludes to who have the money and are listening to their systems, and want the latest great reviewed amp or speakers, and yeah, they are kinda lazy. They want the prestige of the latest Mark Levinson amp. To me, that is not an audiophile… they are really not into the music.
I consider you a serious audiophile who had done his homework... You dont need my advice... But the beginners must be advised about what is essential at any price point... And it is not the gear but the synergy as you already knows it... Anyway you had better knowledge than me about high end gear anyway... 😊
After that necessary synergy with all components it is all the electrical, mechanical and acoustical embeddings which matter BEFORE any upgrade... You already know all that and enjoy a top system now...
All i have to say do not concern you in the least and as i say if i had the money i will ask your opinion about the gear choices...I trust you... All audiophiles are not equal...😁
I am happy with my low cost system though ... It is possible to create minimal acoustic satisfaction at low cost and i succeeded doing it three times...thats all i say... All i ever said here concern beginners not owner of top well embedded system..
